A cutting element comprises a supporting substrate, and a polycrystalline compact attached to an end of the supporting substrate. The polycrystalline compact comprises a region adjacent the end of the supporting substrate, and another region at least substantially laterally circumscribing the region and having lesser permeability than the region. A method of forming a cutting element, and an earth-boring tool are also described.
